Lumber Dimensions. 2x4s are not actually 2 inches by 4 inches. When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3.5 size. Here are the common sizes of lumber, and their actual sizes.
Floor Joists. The floor joists comprise the bulk of the floor thickness. Standard floor joists are usually 2-by-10 or 2-by-12 dimensional boards, installed on edge. The actual width of those boards, however, isnât identical to what their name implies.A 2-by-10 joist is really only 9 1/4 inches wide and a 2-by-12 is only 11 1/4 inches wide, so depending upon which size joist the blueprints call for, they will add the respective measurement to the thickness of the floor.Subflooring only adds 3/4 inch to the floor thickness.he actual width of those boards, however, isnât identical to what their name implies.
